The error message suggests potential network issues. To solve the problem, try some of these steps:

  • Verify your NI Linux Real-Time controller is connected to the network and has internet access. Run the ping download.ni.com command on the controller to test the connection with the download site.
    • If this step fails, check the Network Settings of the controller in NI MAX to make sure the controller is able to connect to download.ni.com.
  • Format the controller with the latest version of the NI Linux RT base image.
  • As workaround, run an offline installation of the software.
  • If using SystemLink and a replicated offline feed, review the settings in NI Web Server Configuration are correct. In particular, if using a Public Network, enable Also accept connections from public networks or change the connection in Windows to a different profile e.g. Private, Work or Home. NI Web Server Configuration - Allow Public Networks
